To all whom it may concern:

Be it known that I, DAVID F. GARvEY, a citizen of the United States, anda residentl of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Flushing Apparatus,of which the following is a full, clear, and exact description.

The invention relates to flushing apparatus for waterV closets and itsobject is to provide apparatus of that class in which water is heldunder pressure of air in a closed tank with a j et by which water fromthe supply main will be used to accelerate the flow to the closet whenthe controlling valve is open. Another object of the invention is toprovide an improved apparatus of this class.

The drawing is a side elevation of apparatus, parts being shown insection.

The flushing apparatus is illustrated in connection with a water closetbowl l of any ordinary or suitable construction and comprises a closedtank 2, a pipe 3 for delivering water from the tank to the bowl, asuitable valve l usually of the type which4 is self closing afterremaining open for a predetermined period, and a supply pipe 5 which isconnected to the water supply main. Supply pipe 5 comprises a member 6which eX- tends downwardly through a portion of the vertical member 3 ofthe pipe 3 to serve as a jet by which the pressure of the water in thewater supply will be utilized to force water to the bowl. Pipe 3a isgreater in diameter than the pipe 6 so that during a flushing operationwater from the tank and from the supply 5 will flow to the bowl. Pipe 3comprises a horizontal member 3b which is connected to the verticalmember 3 by a suitable fitting 7 and a downwardly eX- tending verticalmember 3c which passes through the top of the tank 2 and has its loweropen end terminating near the bottom of the tank.

In operation, the valve 4l will be normally closed and water will bedelivered through the pipe 6 into the member 3a from which it will flowthrough members 3b and 3c and be discharged adjacent the lower end ofthe closed tank 2. As the column of water rises in the tank, the tank,the air between the column and the top of the tank will be compressed sothat when the valve 4 is open to flush the closet, air under pressurewill cause the water to flush the bowl. During this flushing operation,the water from pipe 6 will act as a jet which will supplement thepressure of the water from the tank 2 so that the flushing effect willbe increased thereby.

If the air pressure in the tank should be dissipated, the water will besiphoned from the tank by the action of the jet 6.

In practice, it has been found that when the tank is not emptied for aconsiderable period, the air pressure will decrease and that by usingthe jet pipe 6 the water will always be forcibly drawn from the tank anddelivered to the bowl under pressure. It has also been found that-byextending the pipe 3C so as to deliver the water in a downwardlydirection, there is less tendency t0 mix the air and water and as aresult an effective air pocket will always be formed.

The invention is not to be understood as restricted to the details setforth, since these may be modified within the scope of the appendedclaims, without departing from the spirit and scope of the invention.

I-Iaving thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a flushing apparatus, the combination of a closed tank, aflush-pipe connected to deliver water to and from said tank, a valve forcontrolling the discharge of water from the flush-pipe, and a supplypipe provided with a j et extended into the flushpipe to force waterthrough the flush-pipe and toward the valve.

2. In a flushing apparatus, the combination of a closed tank, aflush-pipe connected to deliver water to and from said tank comprising avertical member, a valve for controlling the discharge of water from theflush-pipe and a supply pipe provided with a vertical jet-pipe in saidvertical member and discharging water downwardly, to force it toward thevalve.

3. In a flushing apparatus, the combination of a closed tank, aflush-pipe connected to deliver water to and from said tank, andcomprising a member extending downwardly and having its lower end nearthe bottom of the tank and open, a valve for controlling the dischargeof water from the flushing pipe, and a supply pipe connected to deliverthe tank and open, a valve for controlling water/into the lushfpipe andforce it toward the discharge of water vfrom the flushing 10 the valve.piping-andra supply-pipe provided-with a jet Y 4;. In a, flushingapparatus, the oombinain the flush-pipe to Siphon water from the 5 tionof a closed tank, a flush-pipe connected tank through said member andforce it toto deliver water to andffromsaidtank, land ward the valve.comprising a member extending downwardly and having its lower end nearthebottom of DAVID F.
